SPECIFICATION forming part of Letters Patent 110354.743, dated December21, 1886.

Application filed October 6, 1886. Serial No. 215,441. (No model.)

T0 on whom it may concern:

Be it known that I, JOHN SABOLD, a citizen of the United States,residing at Little Oley, in the county of Berks and State ofPennsylvania, have invented certain new and useful Improvements inIngot-Molds, of which the following is a specification.

This invention relates to improvements in ingot-molds, and isillustrated in the accompanying drawings, in which- Figure 1 is a broadside view of the mold, showing the upper right-hand corner broken awayfor the purpose of better illustration. Fig.2isanarrowsideview ofthemold. Fig. 3 is an elevation of the flange on each mold-section. Fig.4 is a horizontal crosssecti'on of the mold on the line :0 :17. Fig. 5is a top, end view of the mold. Fig. 6 is a view of the shield-plate.Figs. 7, 8, and 9 are detail views of the improved clamping device.Figs. 10 and 11 are views of the end-lift ears. Fig. 12 is a view of oneof the side-lift bars. Figs. 13 and 14- illustrate the manner of liftingthe mold by the end and side, respectively. Fig. 15 is an end view ofthe mold showing the side-lift bars in position.

The letter A designates one section and B the other of a metal mold.These two sections are in all respects alike and may be produced by acast taken from the same pattern. These two sections unite at the narrowsides, which are opposite each other and are separable at the unitingedges 0 of said narrow sides. By reference to Fig. 3 it will be seenthat the uniting edges are rabbeted in a special manner. This rabbetconsists of an angular groove,- 0, and a tongue, 0

Each section A B has an angular groove and a tongue on each ofv itsuniting edges, but those at one uniting edge have a reversed relaativeposition from those at the other edge. Each mold-section at one edge hasthe angular groove 0 on the outer side and the tongue 0 on the innerside, and at the other edge the angular groove 0 is on the inner sideand the tongue'c on the outer side. It will thus be seen that while thetongues of one mold-section fit in the grooves of the other section theposition of these parts at one uniting edge is reversed from those atthe other edge, whereby any slight variation, like a warp or twist atthe edges, due to the shrinkage of the casting,

will not prevent a close fit or union of thetwo mold-sections, inasmuchas the bolts will draw the partstogether.

Each mold-section has at one of its narrow sidesone or more wrought-ironlugs or pins, 12, which are secured by being cast into the metal formingthe mold, the said pins being embedded in a boss, q. These lugs or pins12 are on the narrow side only which has the angular groove outermost,(see Fig. 3,) and each pin projects horizontally and across the unitingedge 0 and laps over onto the next moldsection. As thepins p are made ofwrought- 6 iron, their proj ecting ends may be bent slightly toward oraway from the angular groove by slight blows made with a hammer, andthereby made to fit properly in contact with the tongue of the nextmold-section.

The two narrow sides of eachv mold-section A B are each provided with aflange, d,which may extend continuously from top to bottom, or mayextend at intervals only, with spaces between. The flange d on eachsection is a 7 short distance away from the uniting edge 0, whereby aseparating-space, e, is left between the two flanges which are on thesame side of the mold. The flanges have bolt-holes f for the bolts f,and also have'on the outer side a slit or slot, f*, at each bolt-hole.This slot provides against any detrimental effect on the flange, such ascracking, when sudden expansionor shrinkage ensues.

A feature of this invention is the double- 8 inclined or double-wedgeclamp device used in connection with the flanges d and bolts f, forquickly loosening the two mold-sections, either to permit the extremeexpansion of metal that ensues when all theparts are highly heated or toallow the ingot-casting to be removed from the mold. The object ofmaking these devices double is to provide for the mold being reversedend for end or turned upside down. The double-wedge clamp devicecomprises two movable bars or drop-bars, G, one at each narrow side ofthe mold-section. Each dropbar G is provided on one side with one or Imore double-inclined blocks, h, the inclination mo of which is in thedirection of the length of the bar. The two highest parts, h, of theinclination are at the upper and lower end, and the lowest part, h ofthe inclination is at the center between thesaid twohigh ends. The

double-inclined blocks (see Fig. 8) are partly divided up and down thecenter by a slot, f,

which also opens entirely through the bar Gr.

Upon each bolt f is a loose wedge, k, the highest part, k, of theinclination of which is'at the'center, andfrom thence it inclines ortapers both ways to the two thin ends h. The

double wedge is has at its center an elongated bolt-hole, f, (see Fig.9,) whereby when it is in position on the horizontal bolt f its centerpoint, k, will be below the center of said bolt, and the nut 0, incontact with the straight or flat side of the wedge, will bear mostly onthe r upper part, and thereby keep the upper in- W cline or upper wedgepart in contact with the block h. By virtue of the elongated bolt-holethe double wedge k,when the mold is reversed end for end, may drop onthe bolt f, so as to bring its other incline in the same relativeposition on the bolt. It is not essential, however, for the wedge 70 tohave an elongated bolt-hole.- The loose double wedge has a lug, l, atone or both inclined ends, and its doubleinclined side confronts thedouble -inclined block h, and the lugs l on the wedge occupy the slot fon the block and prevent the wedge h from turning on the bolt. 4

In consequence of the repeated heating and cooling the cast-metalmold-sections A B are liable to crack and burst open. Therefore toprovide against injury to the ingot in the event of the mold crackingeach cast-metal section has cross-bars H and longitudinal bars 11 ofwrought metal embedded in its sides. The ends of each wrought-metal bararebent to a position at right-angles with the bar and penetrate thecast metal, while the bars between the said ends are partly exposed. 0It is obvious the bars, instead of being partly exposed, may be entirelyconcealed in the body of the cast metal. If '-the mold-sections crack,these wrought bars serve to prevent a separation of the parts. 7

Shield-plates I are provided to lie on top of the mold, as shown inFigs. 1, 2, and 5, and \are secured in position by the lift-earshereinafter referred to.

Two detachable lift-ears, J, are provided for lifting the mold endwiseto allow the ingot to drop out, and also to lift the drop-bar G andloosen the clamps. Each lift-ear is so constructed and attached to themold as to accomplish these two ends. Each lift-ear fits loosely in twogrooves, n, one of which is on each flange, d, of the mold near the end,the two grooves 'n are on sides of the flange which confront each other,and the lower end of the ear is too thick to enter the said grooves.Eachear J is attached to across-bar, T, which extendshorizontally acrossthe separating,v

space between the two flanges and loosely occupies a slot, 8, in eachflange, as shown in Fig. 3. This slot 8 extends in a direction up anddown, and normally the ends of the crossbar r rest in the lower end ofthe said slots.

Therefore upon lifting the ears J the cross-bar T will be raised in theslots. This construction of grooves n and a lower end on the ear toothick to enter said grooves causes a portion of the lifting-strain tocome directly on said thick lower end, and thereby relieves thecross-bar and prevents it from bending. The ears are detachable, andhave position at the uniting edges o of the two mold-sections, and thecrossbar which secures each ear occupies a slot in differentmold-sections. Thereby when the mold is lifted the two sections are freeto spread apart and allow the ingot to drop out. One end of eachcross-bar r has a projecting point, r, and each end'of' the drop-bars Ghas ahole, t, and the said projecting point occupies one of these holes.The parts are so proportioned and arranged that the double-inclinedblock h will be resting against or crowdedldown on the wedge-block k atthe same time that the cross-bar r is seated in the lower end of theslots 8. When the hooks u on a chain, u, are engaged with the lift-earsJ, as in Fig. 13, the; first effect of lifting is to raise the drop-barsG a certain distance-that is to say, until the center part, h, of theblocks h have position coincident with the center part, k, of the otherblocks, k -whereupon the clamp device f h k is relaxed suflicient toallow the two sections A B of the mold to separate or slightly spreadapart, so that the ingot is loose in the mold, and then the secondeffect of continued lifting by the ears J is to raise the mold, upondoing which the ingot will drop out.

The shield-plates I, before described, have a slot, 12, which isoccupied by the lifting-ears J. These latter secure the plates inposition, and

said plates prevent the molten metal from.

reaching the grooves n) and cross-bar r, where the ears are attached.

The narrow sides of the mold are provided with two lift-bars, w, theends a: of which fit loosely in the flanges (1. These lift-bars arecurved at the center, and serve, as shown in Fig. 14:, to receive thehooks'u of a chain, u, whereby the mold may be lifted sidewise. This isfrequently necessary.

Molds of this class burn or become damaged at the bottom first, and whenone end has become injured to such an extent as to be no longerserviceable for the bottom I provide, by the construction here shown ofthe clamp device, for reversing the mold end for end, or turning itupside down. To do this it is sim* ply necessary to lay the mold down onits flat side, draw out the cross-bar 1, and detach the lift-ears J, andthen attach them to the other end, which may then be raised. Uponreversing the mold the drop-barG and clampdovices f h k adjustthemselves automatically.
